TELEGRAPH-KEY.

Specification of Letters Patent.

Patented Sept. 28, race.

Application filed. January 28, 1909. Serial No. 474,674.

To all whom it may concern:

Be it known that I, Gnonon Srmtrnn Puimv, a citizen of the UnitedStates, residing at Branford, in the county of Suwanee and State ofFlorida, have invented a new and useful Telegraph-Key, of which thefollowing is a specification.

This invention relates to telegraph transmitters and more particularlyto an attachment for relieving the operator of the strain incident totransmitting messages under the well known Morse system.

The object of the invention is to permit the sounding of alettercomprising a plurality of dots with a single movement of theoperating lever, thereby to expedite the transmission of messages and atthe same time relieve the operator of the strain clue to the necessityof imparting a plurality of strokes to the operating key to produce suchletter.

A further object is to provide an instrument capable of sounding eitherdots or dashes, and which may be used, either in connection with orindependent of the usual form of telegraph key.

A further object is to provide an instrument of the character described,the construction and operation of which is such as:

to permit a solid contact between the platinum pointer, and which may beadjusted to make either light or heavy dots or dashes.

A still further object of the invention is generally to improve thisclass of devices so as to increase their utility, durability andei'liciency.

Further objects and advantages will appear in the following description,it being understood that various changes in form, proportions and minordetails of construction may be resorted to within the scope of theappended claims.

In the accompanying drawings forming a part of this specification:Figure1 is a alan view of a tele ra 3h transmitter constructed in accordancewith my invention showing the position of the parts when making a dash.Fig. 2 is asimilar view showing the position of the parts when making adot. Fig. 3 is a longitudinal sectional view taken on the line- 3-3 ofFig. 2. Fig. 4: is a similar view taken on the line 4t4; of Fig. 2. Fig.5 is an end elevation. Fig. 6 is a transverse sectional view taken onthe line 66 of Fig. 2. Fig. 7 is a perspective view of the oscillatingcontact member detached.

Fig. 8 is a similar view of a portion of the vibrator. Fig. 9 is a topplan view illustrating a modified form of the invention. Fig. 10 is aside elevation of Fig. 9. Fig. 11 is a transverse sectional view takenon the line 11 11 of Fig. 10.

Similar numerals of reference indicate corresponding parts in all of thefigures of the drawings.

The telegraph transmitter forming the subject matter of the presentinvention comprises a base plate 5 to which is secured a relativelyshort side wall 6 and an end wall 7, said walls being connected by a topplate, indicated at 8.

Pivotally mounted on a stud 9 extending vertically from the base is akey lever 10, one end of which is provided with a vertical extension 11,while the other end thereof projects longitudinally beyond the pivot 9to form a finger piece 12.

Extending longitudinally of the base above the operating lever 10 is avibrator 13 having its inner end formed with an enlarged head 14, whichlatter is pierced by a pivot pin 15, the terminals of which are conicalin shape and engage correspondingly shaped sockets formed in adjustingscrews 1.6 and 17 carried by the cap-piece 8 and base 5, respectively,as best shown in Fig. 3 of the drawings. This vibrating lever 13 ispreferably formed in two sections, the main section 18 of which isformed of relatively stiff material having a slight spring action andthe auxiliary section 19 formed of relatively thin material, so as topermit the latter to readily vibrate.

Extending transversely through the secions 18 and 19 of the vibratinglever, at the junctureof said sections, are one or more rivets orsimilar fastening devices 20 which serve to hold the sections rigidly inlongitudinal alinement with each other.

An oscillating lever 23 is pivotally mounted on the platform at 2% andis provided at one end with a bifurcated terminal 25 which receives anadj usting screw 26 extending laterally from the inner end of the mainoperating lever 10. e

The contact 22 of the oscillatin lever is provided with a platinum point21 for en gagement with a similar platinum point 28 carried by anadjusting screw 29 threaded in the'side wall 6, one terminal of thecircuit being connected with the clamping nut of the contact 22 and theother terminal thereof connected with a binding screw 30 on the member29.

Extending laterally from the head 14 of the vibrating lever is a pin 32to the free end of which is connected one end of a coiled spring 33, theopposite end of which is connected with a pin or stud 34, said springserving to return the vibrating lever to normal position after theplatinum points 27 and 28 contact with each other to make a dot. Acoiled spring 34 is also preferably interposed between the wall 6 andthe oscillating lever 25 for returning the latter to normal positionafter each operation of the finger-piece. Thus it will be seen that bymoving the finger-piece 12 laterally in the direction indicated by thearrow shown on the finger-piece in Fig. 2 of the drawings the extension11 of said lever will engage the section 18 of the vibrator and forcethe latter against the contact 22 of the oscillating lever 23 thustilting said lever and causing the platinum point 27 of the oscillatinglever to close the circuit through the platinum point 28 of theadjusting screw 29 and sound a dot.

The vibration of the lever 13 will cause the contacts 27 and 28 tointermittently open and close the circuit, the number of dots producedat each movement of the finger piece 12 being in proportion to thenumberof vibrations of the lever 13.

Slidably mounted on the section 19 of the vibrator is a weight whichgoverns the vibration thereof so that by moving the weightlongitudinally of the section 19 and clamping the same in adjustedposition by tightening the screw 36 the number of dots sounded at eachmovement of the lever 12 may be governed at will.

" bration of the weight 35 after the hand of The inner end of the fingerpiece 12 is provided with an over-hanging cylindrical arm 37 on which isloosely mounted a sleeve or collar 38, which latter serves to stop vitheoperator has been removed from the finger piece 12.

By moving the finger piece 12 in the directlon, indicated by the arrowin Fig. 1 of the drawings, the extension 11 will be disengaged from thevibrating lever and the oscillating lever 23 actuated to produce dashes.

The screw 26 is provided with an enlarged head 38 which bears against astop screw 39 threaded in the wall 6, there being a washer 40 interposedbetween the head 38 and the adjacent side of the oscillating lever toassist in preventing the head 38 from passing through the bifurcatedportion of said lever.

By arranging the several parts in the manner described, a firm solidcontact between the platinum points 27 and 28 is assured, the line up oradjustment of the main lever 12 and vibrating lever as well as thelength of stroke of said levers being obtained by manipulating thescrews 26 and 39 and eitherlight or heavy dots or dashes by adjustingthe screw 29-. Thus it will be seen that by moving the finger piece 12in one direction, the instrument may be utilized for sounding dots,while by moving the finger- If desired, the attachment may be used inconnection with an ordinary telegraph key and for this purpose one sideof the base 5 is formed with a segmental recess 41 intersected by alongitudinally disposed groove 42, preferably dovetailed in crosssection, and

in which is mounted for sliding movement a wedge shaped key 43.

When the device is used in connection with a telegraph key the frame. ofthe key, indicated at 44 in Fig. 1 of the drawings, is positioned at thesegmental recess 41 with the finger-piece 44 thereof adjacent thefinger-piece 12 and in convenient position for manipulation by theoperator, the operator first operating the finger-piece 12 of thepresent attachment to sound the dots in the Morse alphabet and thenoperating the finger-piece 44 of the ordinary telegraph instrument toproduce the dashes. As before stated, however, the attachment iscomplete in itself, and may be used for sounding both dots and dashes.

The attachment is clamped in position on an ordinary telegraph keyby'moving the locking key 43 longitudinally within the slot 42 until therecess or depression 43 of said locking key passes beneath the adjacentpivot screw 45 of said telegraph key, as best shown in Figs. 1 and 6 ofthe drawing and in which position the attachment will be locked againstaccidental displacement without the employment of screws, clamps andsimilar fastening devices.

The device is very sensitive and the parts thereof may be adjusted toproduce sounds corresponding to light or heavy dots or dashes, while theweight 35 may be adjusted to produce any desired number of vibrationsand thus permit the sounding of any number of dots at one operation ofthe finger-piece.

Special stress is laid upon the fact that by means of the oscillatinglever 23 and platinum points 27 and 28 a firm solid contact is insuredat each movement of the main operating lever, while by manipulating theadjusting screws 26, 29 and 39 not only, may the throw'or stroke of themain and vibrating lever be regulated at will but the contacts adjustedto make either light or heavy dots or dashes.

In Figs. 9 to 11 of the drawings there is illustrated a modified form ofthe invention in which the side and end walls of the supporting base aredispensed with, the head 47 of the vibrating lever 13 being pivotallymounted in an over-hanging bracket 48 secured to one end of thesupporting base. In this form of the device the key lever 10 is maderelatively thin and of substantially the same cross sectional diameterthroughout its entire length, one end of said key lever being providedwith a finger-piece 12 similar in construction to the finger-piece shownin Fig. l of the drawings, while the opposite end thereof of the keylever is connected through the medium of a link or plate 49 with theoscillating lever 23.

The upper lon itudinal edge of the connecting plate or link is formedwith a longitudinally disposed slot 50 for the reception of a clampingscrew 51, which latter is threaded in the adjacent end of theoscillating lever 23, the movement of the oscillating lever 23 beingregulated by a screw 52 threaded in the angular extension of the plate19 and engaging the shank of the screw 51, as best shown in Fig. 11 ofthe drawings.

Suitable lugs or brackets 53 and 54.- are secured to the supporting baseat one longitudinal edge thereof and provided with, threaded openingsfor the reception of correspondingly threaded screws 55 and 56, one ofwhich is provided with a contact 57 for engagement with the contact 58of the oscillating lever 23, while the other screw 56 by engagement withthe screw 52 forms an auxiliary stop for said oscillating lever.

Extending laterally from the head of the key lever 13 is a pin or lug 59to which is secured one end of a coiled spring 60, the opposite end ofwhich is attached to a cord or other flexible medium, which latter issecured to a screw 61 threaded in the oscillating lever 23. The spring60 serves to return the vibrating lever, key lever and 0s cillatinglever to normal position after the finger-piece 12 has been actuated tomake either dots or dashes. The lower face of the oscillating lever 23is preferably cut away, as indicated at 61 so as not to interfere withthe action of the spring 60 when said lever is oscillated.

As the construction and operation of the device'shown in Fig. 9 isotherwise similar in construction to that shown in Fig. 1 of thedrawings, further explanation of the same is deemed unnecessary.
